Course Abstract:
In this hands-on workshop, we will introduce the philosophy and science of chemical reaction engineering simulation and parameter estimation. We will describe key elements of a model-based approach to data analysis, including methods for validating important statistical assumptions that undergird the parameter estimation process. The workshop will include hands-on components with code that we will provide in advance, using AthenaVisual Studio to illustrate some key concepts. Then, we will provide a workshop example where we will demonstrate the utility of reactor and kinetic modeling for experimental data analysis, using a real-world trickle bed scale-up problem. In the workshop, we will use a parameter estimation case study provided in advance to perform kinetic parameter estimation for three alternative models and use model discrimination to rank the models. Based on our model-aided analysis, we will identify potential issues with the experimental data and show how this analysis leads to a better model and, therefore, better understanding of the physical system. We will also demonstrate statistical evaluation protocols that should be followed regardless of the modeling tool employed.

We ask students to bring a laptop to the session with at least a trial version of the AthenaVisual Studio software installed. Because this is not a software training session, we encourage new users to spend a few hours gaining familiarity with the tool before the workshop. We will provide one or more tutorials to registered students to guide their independent learning prior to the workshop

Course Abstract:
Developed by the Core R&D Reaction Engineering group of The Dow Chemical Company and designed for chemists and engineers who operate or use data from laboratory reactors, this course contains fundamental reaction engineering knowledge essential for generating high quality data from a laboratory scale reactor. The course content includes general principles and practical tips for designing and operating laboratory reactors. The bulk of the course content focuses on stirred tank, homogeneous tubular, and fixed bed reactors for a variety of reaction systems, including homogeneous liquid phase, gas-liquid, gas-solid, liquid-solid, and gas-liquid-solid systems. At the end of this course, chemists and engineers will have a better understanding of the critical factors affecting the performance of laboratory scale reactors and the appropriate means for addressing those factors to maximize the probability of generating quality data. During this course, the instructors will introduce a publicly available tool for estimating gradients in heterogeneous catalyst particles and for sizing laboratory fixed bed reactors. This tool is the product of a collaboration between Dow and Purdue University.

Course Abstract:
Aligned with the theme of NASCRE-5, Breaking Barriers for a Sustainable Future, this workshop invites participants at all career stages—students, postdocs, professors, and industry professionals—to explore how “Inclusive Innovation” can transform science and engineering fields for a more sustainable world.

Sustainability requires breaking down the social, environmental, and economic barriers posed by global challenges. As engineers and scientists, our role goes beyond addressing technical problems—it involves ensuring that our solutions benefit society broadly and equitably. Inclusive innovation redefines how we address these challenges by integrating diverse perspectives and equitable practices into sustainable process development. It also calls for a critical assessment of our research, ensuring that marginalized and underrepresented communities are not overlooked.

Inclusive environments foster psychological safety, where everyone feel comfortable voicing concerns and ideas without fear of retribution. This openness can lead to better safety practices and quicker identification of hazards, especially during experiments or group activities.

This workshop emphasizes the importance of diversity, equity, and inclusion—across multi-facets dimensions—in driving innovation within academia and industry. Collaboration among diverse teams can challenge biases and work towards solutions with broader impact. Equity ensures fair access to opportunities and promotes social and environmental justice.

Participants will engage in panel discussions, case studies, and group activities that link inclusion and equity with chemical reaction engineering. The workshop will begin by addressing biases in research environments fostering representation and equitable opportunities through a panel discussion. Further, the participants will explore social and environmental justice aspects of decarbonization, energy transition, and plastics recycling through group activities and case studies. These discussions will inspire actionable strategies to drive global sustainability.

Course Abstract:

This workshop will involve a panel discussion from the following three current/former Chief Scientists or Vice President at Fortune 500 companies:

• Shailendra Bordawekar, Vice President, AbbVie
• Jennifer Ward, Chief Scientist, ExxonMobil
• Joseph Powell, former Chief Engineer, Shell

These industrial researchers will each discuss their respective, unique paths to succeeding and making key contributions on the technical ladder industry. Their brief biographical presentations will be followed by a discussion about the skills – both technical and non-technical – and professional habits/attitudes that played a critical role in their success in large research organizations. This workshop is targeted toward graduate students, postdoctoral associates, and early career researchers, and will endow them with a stronger sense of aspects (over and above technical skills) that are critical to successfully embarking on a career on the technical ladder in industry. Students and early career researchers with an interest in industrial careers are strongly encouraged to attend.
